propeller cavitation noise 螺旋桨空泡噪声
propeller sheet cavitation 螺旋桨片空泡
The effective wake is one of the primary reasons of propeller cavitation and induced ship hull vibration.
实效伴流的不均匀性是引起螺旋桨空泡、振动的主要原因之一。
It is shown that propeller cavitation noise is composed of continual spectrum and separable line spectrum.
结果表明，螺旋桨空泡噪声由连续谱和离散线谱组成。
On the basis of above theoretical model, the spectrum formula of propeller cavitation noise has been derived.
据此理论模型，导得螺旋桨空泡噪声谱的表达式。
